A) The amount of change is .20 (20 cents) so we need to find what percent of $4.00 is .20...
4 * x = .20
x = .20/4 = .05
Multiply by 100 (move decimal 2 places to the right) to change decimal to percent.
.05 = 5% increase
b)The increase is .75. What percent of 3.00 is .75
3 * x = .75
x = .75/3
x = .25 x 100 = 25% increase
c) The amount of change is .75 but this time we are going from 3.75 to 3.00 so we find out what percent .75 is of 3.75.
3.75 * x = .75
x = .75/3.75
x = .20 x 100 = 20% decrease
Answer:
a. x = -4
c. x = 9
Step-by-step explanation:
Values of g(x), output values, are plotted on the y-axis, while the corresponding x values, input, of the function are plotted on the x-axis.
We are to determine all possible input values (x-values) that will give us an output value, g(x) = 8.
On the graph, look at the point where y = 8, on the y-axis. When y = 8, we have two possible values of x. They are -4, and 9.
Thus:
g(-4) = 8
g(9) = 8.
The possible input values for which g(x) = 8, are x = -4, and x = 9.
If the pre-image is on the left, then it moves to the right and up to transform into the new image (diagonal pointed to the upper right).
If the pre-image is on the rightt, then it moves to the left and down to transform into the new image (diagonal pointed to the lower left).
Answer: A and F
You should first turn 1 5/8 into an improper fraction. 1 5/8= 13/8. For fractions, you just multiply regularly.
Let’s do the numerators first (the top number):
2 • 13 = 26
Now the denominators:
3•8= 24
The fraction would be 26/24, but this can be simplified smaller. Let’s divide the top and bottom by two (trick when simplifying is to divide by smaller numbers if you can like 2,3,4).
We now have 13/12, and since 13 is prime, that is the farthest we can simplify to. Let’s make it a mixed number, 1 1/12 is the answer.
375 hamburgers were sold on Wednesday
<em><u>Solution:</u></em>
Let "h" be the number of hamburgers sold
Let "c" be the number of cheeseburgers sold
To find: number of hamburgers sold on Wednesday
Given that local hamburger shop sold a combined of 686 hamburgers and cheeseburgers on Wednesday
Therefore,
number of hamburgers sold + number of cheeseburgers sold = 686
h + c = 686 ------- eqn 1
There were 64 fewer cheeseburgers sold than hamburgers
Number of cheeseburgers sold = number of hamburgers sold - 64
c = h - 64 ------- eqn 2
Let us solve eqn 1 and eqn 2
Substitute eqn 2 in eqn 1
h + h - 64 = 686
2h - 64 = 686
2h = 686 + 64
2h = 750
h = 375
Thus 375 hamburgers were sold on Wednesday
